1. What does antidiuretic hormone (ADH) help the kidneys regulate?

• A. Acid-base balance
• B. Blood pressure
• C. Urine output by controlling water reabsorption
• D. All of the above

Correct answer: C

Rationale: Antidiuretic hormone (ADH) helps the kidneys regulate urine output by controlling water reabsorption. ADH acts on the kidneys to increase the reabsorption of water, leading to a decrease in urine output. This helps the body conserve water and maintain proper fluid balance. ADH primarily affects urine output by controlling water reabsorption and does not directly regulate acid-base balance or blood pressure. Therefore, choices A and B are incorrect because ADH does not directly influence acid-base balance or blood pressure.

2. Which structure of the endocrine system is responsible for maturing T cells?

• A. Hypothalamus
• B. Pineal
• C. Thymus
• D. Thyroid

Correct answer: C

Rationale: The thymus is the primary gland responsible for the maturation of T cells in the immune system. T cells are a type of white blood cell involved in the immune response. The hypothalamus is primarily involved in hormone regulation and maintaining homeostasis. The pineal gland is responsible for secreting melatonin and regulating the sleep-wake cycle. The thyroid gland plays a key role in metabolism regulation through the production of thyroid hormones. Therefore, the correct answer is the thymus because it is specifically associated with the maturation of T cells, making it essential for proper immune function.

3. Solve |x| = 10.

• A. -10, 10
• B. -11, 11
• C. -12, 12
• D. -13, 13

Correct answer: A

Rationale: The absolute value of x is equal to 10 when x is either -10 or 10. Therefore, the correct answer is A. Choices B, C, and D are incorrect because they do not satisfy the equation |x| = 10. For choice B, -11 and 11 do not satisfy the condition. Choices C and D also do not provide solutions that meet the equation's requirement.

4. Which of the following sentences correctly uses a semicolon?

• A. I have a big test tomorrow; I can't go out tonight.
• B. I have a big test tomorrow; I can't go out tonight.
• C. I have a big test tomorrow; and I can't go out tonight.
• D. I have a big test tomorrow; but I can't go out tonight.

Correct answer: A

Rationale: The correct use of a semicolon is to join two closely related independent clauses. Choice A is the only option that correctly uses a semicolon to connect two independent clauses: 'I have a big test tomorrow' and 'I can't go out tonight.' Choice B incorrectly uses a comma instead of a semicolon. Choice C adds an unnecessary 'and' after the semicolon, which disrupts the correct punctuation usage. Choice D introduces a contradictory conjunction 'but' after the semicolon, which is not necessary for the given context. Therefore, the correct answer is A.

5. A teacher notices that, when students are talking to each other between classes, they are using their own unique vocabulary words and expressions to talk about their daily lives. When the teacher hears these non-standard words that are specific to one age or cultural group, what type of language is she listening to?

• A. Slang
• B. Jargon
• C. Dialect
• D. Vernacular

Correct answer: A

Rationale: The correct answer is 'Slang.' Slang refers to informal words or phrases that are specific to a particular group of people, such as young people or a specific culture. In this scenario, the teacher is hearing non-standard words and expressions used by students, which aligns with the definition of slang. Jargon typically refers to specialized terminology used within a specific profession or group. Dialect refers to a particular form of a language that is specific to a region or social group. Vernacular refers to the everyday language spoken by people in a particular region or country.
